TREE SPARROW. 
559. WSpizella monticola. 6% inches. 
A blackish-brown spot in middle of breast; crown 
reddish brown with no black about the head; back and 
wings with considerable brown. 
These Sparrows are summer residents of the Arctic 
region, passing the winter in the northern half of the 
U. 8. They bear considerable resemblance to our com- 
mon Chipping Sparrow, but are larger and have char- 
acteristic markings as noted above. They appear in 
the U. 8S. in October and many of them pass the win- 
ter in the fields and gardens in our northern states. 
Note.—A musical chirp; song, strong, sweet and 
musical and ending in a low warble. 
Nest.—Usually on the ground, but sometimes at low 
elevations in bushes. Eggs pale greenish blue with 
brown specks over the whole surface, thus being very 
different from those of the Chipping Sparrow (.80 x .60). 
Range.—N. A. east of the Plains, breeding in Labra- 
dor and about Hudson Bay; winters in northern half 
of the U. S. A-sub-species, 559a.- Western Tree Spar- 
row (ochracea) is paler; it is found from the Plains to 
the Pacific, breeding in the north.
